The notice has also sought Gambhir to publish the apology along with true and correct facts in newspapers and on social media, within 24 hours, failing which criminal proceedings would be initiated against him.
Hitting out at Kejriwal on Thursday, Gambhir had tweeted: "I feel ashamed to have a CM like Arvind Kejriwal. I abhor your act of outraging a woman's modesty @ArvindKejriwal and that too your own colleague. And all this for winning elections? You are filth Mr CM and someone needs your very own jhadu (broom) to clean your dirty mind."
Mohd Irsad, the lawyer representing AAP, states that the party finds the above tweets by Gambhir as offending.
On Friday, AAP's East Delhi candidate Marlena accused Gambhir of circulating pamphlets with derogatory and casteist remarks against her. The AAP leader filed a complaint with the Delhi Commission of Women (DCW).
Gambhir has, however, rubbished the allegation saying that if proved guilty, he would quit politics. He also sent a defamation notice to Marlena, Kejriwal, and Sisodia, demanding an unconditional apology for making "defamatory" comments against him.
